Question

我正在尝试在将id传递给控制器时返回另一个页面。但是我得到了这个错误：

 Error executing child request for handler 'System.Web.Mvc.HttpHandlerUtil+ServerExecuteHttpHandlerAsyncWrapper'.

视图\ Error_Summaries \ Details.cshtml

  @{Html.RenderAction("FindAllDetails", new { bolnumber = Model.BOL });}

Error_SummariesController.cs

public ActionResult FindRelatedBols(string bolnumber)
{
    if (bolnumber == null)
    {
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }
    Error_Summaries error_Summaries = db.Error_Summaries.SingleOrDefault(r => r.BOL == bolnumber);
    if (error_Summaries == null)
    {
        return HttpNotFound();
    }
    return View("Views/Error_Details/Details");
}

Answer 1

检查内部异常时，它显示正在查看错误的操作名称。我已经指定FindAllDetails而不是FindRelatedBols。此外，返回路径是错误的。最后，我没有使用正确的方法名称。

public ActionResult FindRelatedBols(string bolnumber)
{
    if (bolnumber == null)
    {
        return new HttpStatusCodeResult(HttpStatusCode.BadRequest);
    }
    //var test = 
    //var qrytest = db.Error_Details.Where(r => r.BOL == bolnumber);
    //var details = qrytest.ToList();
    var details = db.Error_Details.Where(r => r.BOL == bolnumber).ToList();
    if (details == null)
    {
        return HttpNotFound();
    }
    return PartialView("~/Views/Error_Details/Index.cshtml", details);
}
